I have a problem. The inside surfaces of every glass panel in my 56 column tank are covered with a milky film. This is not hard water deposit because I have tried several times to clean it up with razor blades and vinegar, but with not effect at all. It seems more like something etched into the glass. I do not know what caused it. I suspect that the tank came with this glass defect because I noticed it not long after getting the tank. I should have returned it, but a couple of months had already passed after purchase and I had it full of water.

I want to get some good pictures of this setup, but it's hard. I have found that I can get a pretty clear shot by wiping down that front panel and shooting real fast before the thin film of water evaporates.

Does anybody have any experience with glass polish? Could I hope to clean this up with glass polish?
